Some of the locations and time periods, such as Fedual Japan and Victorian England, are already popular suggestions among Assassin's Creed fans.

Others have already been hinted at within Assassin's Creed canon. An adventure in Ancient Egypt would fit with hints dropped in this year's Revelations, while Medieval China could fit in to the story told by Revelations' animated epilogue film, Embers, which features Chinese assassin Shao Jun.

A game set during the Russian Revolution, meanwhile, would be set in the same time period as Assassin's Creed graphic novels The Fall and The Chain. They feature the saga of Russian Assassin Nikolai Orelov and his modern day counterpart Daniel Cross.

Other suggestions are more surprising. Would British colonists be the bad guys in a story set during the American Revolution? Would the Spanish be the good guys in a South American conquistador-era tale?
